Definitions

  • the invention relates to a device with a U-shaped bite fork for producing a bite prosthesis.
  • a template with wax bite walls which represent the two rows of teeth, is produced in the patient's toothless mouth.
  • the two templates are attached to the upper or lower model carrier of an articulator in the dental technician's laboratory. In the majority of cases, these are so-called mean value articulators, in which the bite level is fixed.
  • German patent application P 33 13 198.8 is a device for plastering in of jaw models in the manufacture of dentures with an articulator, which has a lower model carrier for a lower jaw template and an upper model carrier for an upper jaw template, the upper model carrier relative to the lower model carrier by one horizontal axis - the condylar axis - is pivotable.
  • this device has a frame with a base plate for setting up the articulator, with a locking device for fixing the condylar axis of the articulator relative to the base plate and with a table parallel to the base plate for supporting and centering the upper jaw template, the Surface determines the bite plane and which is vertically and sagittally adjustable with respect to the condylar axis.
  • the object of the invention is to provide the dentist with a device with which he can determine the data required for setting the table on the patient.
  • FIG. 1 A side view of a human head is shown in FIG. 1, in which the so-called Camper plane 10 is shown.
  • This Camper plane 10 is an imaginary plane that runs through the two condyle points 12 and the subnasal point 14. It is approximately parallel to the bite plane 16 of the patient and has a distance a from it.
  • FIG. 3 shows a perspective view of a lower jaw 22 in the three-dimensional coordinate system with the vertical axis V, the horizontal axis H and the sagittal axis S.
  • the horizontal axis H connects the two condyle points 12 and is therefore identical to the condylar axis 22. This lies in FIG the camper's level 10, which, as already mentioned, lies parallel to the bite plane with the distance a.
  • prostheses are made by hand biting and with the aid of a commercially available mean value articulator 24 shown in FIG. 6, no consideration being given to the distances a and b shown in FIGS. 1 and 2, which are different for each patient .
  • FIGS. 4 and 5 show a bite fork 26 designed according to the invention, which is bent in a U-shape and has a small elevation 28 at the tip of the bow and is connected to a front bar 32 via a web 30.
  • the front bar 32 merges into a leg 34 on both sides.
  • the two legs 34, the front bar 32 and the bite fork 26 lie in one plane.
  • a leg 34 carries a scale 36, the zero point of which corresponds to the tip of the arch (elevation 28) of the bite fork 26.
  • the zero point of the scale 36 is not exactly perpendicular under the arc tip, but offset by the amount that takes into account the angle between the leg 34 and the front bar 32.
  • a slide 38 is adjustable, which carries a vertical scale 40.
  • the zero point of this scale 40 lies on the top of the leg 34.
  • the bite fork is inserted into the mouth in such a way that the elevation 28 on the front edge of the upper jaw bite template lies in the middle.
  • the upper jaw bite template is designed parallel to the camper's plane 10 on the patient, the bite fork 26 being aligned with its front bar 32 parallel to the bipupillary line 20.
  • the distance a to the camper's plane 10 can be read;
  • the condyle point 12 has previously been made visible on the patient.
  • the distance b is read off on the measurement scale 36 with the aid of the slide 38, which is displaced up to the condyle point 12.
  • the articulator 24 has a lower model support 44 for a lower jaw model 46 and an upper model support 48 for an upper jaw model 50.
  • Two 'condylar columns 52 are fastened to the lower model support 44, between which the upper model support 48 is pivotably mounted via the condylar axis 22. From this condylar axis 22, two stub axles 22 ′ protrude laterally from the condylar columns 52.
  • the lower model carrier 44 also has a mounting plate 58 for the lower jaw model 46.
  • the two model carriers 44 and 48 can be adjusted parallel to one another.
  • circumferential notches are incorporated both in the incisal pin 60 and in the two condylar columns 52, in which a rubber band 62 is fixed in height and thereby the position of the bite plane is determined on the basis of the mentioned mean values.
  • the articulator 24 is inserted into the frame 42.
  • This frame has a base plate 64 with a flat surface, in which the sagittal longitudinal central axis 66 is indicated.
  • the bottom plate 64 carries at each end on its two longitudinal sides two vertical columns 68, on each of which a slide 70 is guided so as to be vertically adjustable. At their upper ends, the two columns 68 of each pair are connected to one another by a spar 72.
  • a horizontally extending locking screw 74 is screwed into each slide 70 in such a way that its tip 76 faces the opposite locking screw 74 and extends coaxially with it.
  • the condylar axis 22 is determined by the two locking screws 74.
  • One of the two slides 70 carries a vertical scale 78, the zero point of which is at the level of the conylar axis 22.
  • the base plate 64 has guides 80 running on its two longitudinal sides in the sagittal direction, each of which receives a carriage 82.
  • the two carriages 82 are firmly connected to one another by a grip bar 84.
  • Two vertical columns 86 are fastened on each slide 82, on which a slide 88 is vertically adjustable by means of an adjusting spindle 90.
  • the two adjusting spindles 90 are connected to one another via a chain drive 98 or the like, so that a table 92 carried by the slides 88 and running parallel to the base plate 64 is always adjusted parallel to the latter.
  • the surface of the table 92 has an arcuate reference line 94 for the upper jaw model 50, the front arc tip 96 of which lies in the center of the table (sagittal center line 100) and is projected onto a reading mark (arrow) on a carriage 82 parallel to the condylar axis 22.
  • the commercially available articulator 24 is placed on the base plate 64 of the frame 42 so that the condylar axis 22 (stub axle 22 ') lies in the same vertical plane as the longitudinal central axis of the two locking screws 74. Then the two slides 70 are on the Columns 68 shifted until the condylar axis 22 of the articulator 24 coincides with the longitudinal central axis of the two locking screws 74. In this position, the two slides 70 are fixed by locking screws 104. The two locking screws 74 are then screwed in until their tips 76 grip the stub axles 22 ′ of the articulator 24 and thus fix the condylar axis 22. It is important to ensure that the articulator 24 is centered with respect to the longitudinal central axis 66 of the base plate 64.
  • the table 92 is then moved so close to the scale 78 by means of the slides 82 which can be displaced in the two guides 80 that the distance a from the surface of the table 92 can be set on this scale 78.
  • the two adjusting spindles 90 which are coupled to one another by the chain drive 98, serve the table height.
  • the table 92 is shifted, as shown in FIG. 8, until the curve tip 96 of the reference line 94 has the previously determined distance b from the condylar axis 22 .
  • This distance b can be set using the arrow on the one slide 82 on the scale 102.
  • the patient's upper jaw template can then be centered on the surface of the table 92 according to the reference line 94.
  • the functional impression is then attached to the upper model template 48 of the articulator 24 in a known manner on the upper jaw template using plaster.
  • a very precise and individual position of the upper jaw template is thus set, so that the full prosthesis or also a partial prosthesis can be produced on the basis of this position.
  • the parallel position of table 92 and base plate 64 ensure parallel plastering in the articulator 24.
